On the virtio_input thread, Michael asked whether each of these patches is a real or a theoretical issue for stable. For this virtio_mmio patch:
Real when the DT node has "wakeup-source". vm_find_vqs() may enable_irq_wake() on the shared IRQ, and vm_del_vqs() used to free_irq() without disable_irq_wake(), which leaves a wake reference and can warn on later free/request cycles. Platforms without that property do not hit it. Please let me know if you still want Cc: stable on this one. Thanks, Xiong
